What do you want to do?

Turn any settings card into a U1/U2/U3 preset. An interactive checklist with the exact menu labels for your body - work straight off the card you downloaded.

Layer frames into one photo, in-camera. Where the mode hides on each body, what the composite options actually do, and which recipes pair well with it.

Answer a few questions - look, light, tone, texture - and walk away with your own settings card, built on measured Image Control behavior. Free.

Every mode on the GR III, IIIx, IV and Monochrome, and what all nine sliders do in which direction, measured on Ricoh's own sample frames. The reference behind every recipe here.

First-day settings from the manual: snap focus and Full Press Snap, the three ISO Auto limits, how U1/U2/U3 and recipes fit together, what to put on the Fn buttons and ADJ lever, and the two things new owners get wrong.

GR III, IIIx, GR IV, the HDF versions, the Monochrome and the coming IVx, compared on the three things that matter: focal length, generation, and what sits where the ND filter used to be.

What changed (sensor, lens, stabilizer, battery, memory, Cinema modes, grain), what did not, how GR III recipes drift on the IV, and an honest used-III or new-IV answer at launch prices.

One difference, the lens: 28mm or 40mm. What each does to street, portraits and travel, why every recipe runs on both, the HDF versions, and which to buy used now that the IIIx is ending production.

Both makers' specs side by side, where each one wins, and the part most comparisons skip: what a JPEG shooter gets out of Image Control against Film Simulation.
